Promoters of plant genes responsive to pathogen invasion
- 65 Downloads
Gene networks controlling the plant resistance to different phytopathogens are rather complex; hundreds of genes can be involved in them. Infection causes considerable changes at molecular-genetic, biochemical, physiological, and morphological levels both locally (in the place of invasion) and systemically. The reconstruction of gene networks that are responsible for plant defense against pathogenic bacteria, fungi, and viruses is required for the elucidation of the underlying molecular mechanisms as well as for the development of new approaches to crop improvement. The transcriptional activity of genes involved in the defense mechanisms usually increases in response to the infection; therefore, the characteristics of their promoters is an important source of information for the detection of transcription factors that control their activity and for the search for new genes involved in the pathogen response. The data on promoters are required for the creation of plants that are resistant to phytopathogens by gene engineering techniques. The data on promoters of pathogen-sensitive genes with an experimentally verified expression pattern annotated in the TransGene Promoters (TGP) database are presented in the article. The TGP database can be used as a source of information for interpretation of transcriptome data and when planning genetically engineered experiments directed towards increasing plant resistance to pathogens of different origins.
